STTRAM Test Module v4.5.19

STTRam module Release Notes

Version 4.5.18: Aug 13 2020
- Fixed: Other than Endurance.1 setup, the default setup values of Endurance test
will trigger exception when executed.
- Fixed: Sometimes, after adding a new "Fail On Parameter" on Endurance test GUI
may trigger exception.
